Glyphosate: Campaigners urge pre-harvest ban; agricultural markets watch

Campaigners and environmental groups have intensified calls to ban glyphosate when used shortly before harvest, arguing the practice leaves residues in staple foods and poses health concerns. The push coincides with a regulatory review period that has put pressure on officials to reassess permitted uses.

The coalition behind the appeal includes the Soil Association, Nature Friendly Farming Network, Greenpeace, Riverford and The Wildlife Trusts, which sent an open letter urging the government to end pre‑harvest desiccation uses. Campaign materials cite testing that found detectable glyphosate residues across numerous wheat, barley and oat samples and estimate the affected area runs into hundreds of thousands of hectares. The timing is significant as the UK’s licensing and consultation timetable draws nearer.

Farming groups and industry representatives warn that a ban could raise costs and complicate harvest logistics, particularly in regions with narrow or unpredictable harvest windows. Industry estimates put the economic role of glyphosate in crop production at substantial levels, and producer organisations argue that removal of pre‑harvest use would require investment in alternative practices or inputs. Markets could see near‑term disruption in commodity handling and processing margins if operational practices must change rapidly.

The debate sits within a broader policy context: the EU banned pre‑harvest use of glyphosate in 2023, and ongoing sanitary and phytosanitary (SPS) talks with the EU increase the incentive for regulatory alignment. The UK Health and Safety Executive (HSE) has extended current approvals to allow a full safety review, with a public consultation due ahead of a final decision on long‑term authorisation. Any alignment with EU rules or restrictive renewal conditions would have knock‑on effects for trade and domestic production economics.

Analysts say investors should monitor regulatory announcements, industry group responses and potential government support measures for farmers transitioning away from the practice. In the near term, agrochemical producers, certain agribusiness suppliers and commodity processors face headline risk and possible re‑rating if restrictions are confirmed. Longer term, the market will price in the cost of alternatives, shifts in crop quality parameters and any changes to export market access that result from alignment with EU standards.
